Your first line of defense against unwanted intruders in your home is a properly locked door. When arranging for reliable home security, it is best to be proactive in replacing locks. If cost is that one factor hindering you from replacing your old lock, it can cost a lot more if it is not done before the lock malfunctions. To avoid late night calls to 24 hour locksmith services, keep an eye open for signs that your locks need to be replaced.

Wear and tear
Rusted and worn locks are a serious threat to home security. The worst part is that, while they are easy to pick and break, they are more difficult to open legitimately with a key. If your lock has severe rust, tarnish or other signs of wear, it's time to replace your locks. If your lock is becoming increasingly difficult to open with the key, especially on cold nights, you need to replace or service the lock immediately to avoid an inconvenient malfunction that may leave you locked out.

Break-ins
If you have had a break-in, you must replace your locks as soon as possible. A damaged lock will put you at a higher risk of another robbery, and mechanical failures as a result of the damage can cause a lock malfunction that could leave you locked out in the cold.

Lost keys
For improved security, you must replace or re-key your locks if your keys are lost or stolen.

New Roommate
If you rent out space in your home, replace or re-key the locks every time you change tenants. You will gain peace of mind knowing that your locks are secure and protected.
